Cleveland Golf Jobber Drill 12.5mm

This cobalt steel jobber drill bit measures 12.5mm in diameter with a 135-degree split point. It meets National Aerospace Standards 907 Type J for heavy-duty applications. The right-hand cutting spiral flute design suits professional machinists and maintenance technicians requiring precise hole-making in tough alloys.

Straw bronze finish with 151mm overall length

The straw bronze surface treatment identifies the cobalt composition while reducing friction during operation. A 101mm flute length provides ample chip evacuation space for deeper holes. The 12.5mm shank diameter matches the cutting diameter for direct chucking without reduction sleeves or adapters.

Replaces worn high-speed steel bits in aerospace

Upgrade from standard HSS drills when machining stainless steels, titanium or nickel-based superalloys where heat resistance and edge retention are critical. The split point geometry eliminates centre punching and reduces walking on curved surfaces. Not suited for coolant-through operations or left-hand threading requirements.

Questions about this item

What does the 135-degree split point on this cobalt drill do for centering?

The 135-degree split point reduces walking and starts the hole on contact without a centre punch.

Will the 12.5 mm shank fit a standard 1/2-inch drill chuck?

The shank is 12.50 mm, slightly larger than 1/2 inch, so it needs a 13 mm or larger capacity chuck.

How do I avoid snapping the bit when drilling 12.5 mm holes in stainless steel?

Use low RPM, steady pressure, and cutting fluid; the cobalt steel handles heat but the 101 mm flutes need chip clearance.
